(33/5 : 6 - 8 •0.125+ 2/15•0.3): 1/5
[ (0.125)^5 ×(2.4)^5] :[(-0.3)^5 ×( 0.01)^3]
X= ( 6 3/5 : 6 - 0.125 x 8 + 2 2/15 x 0.03) x 11/4
cách tính phép tính x=(6 3/5 : 6 - 0.125 x 8 + 2 2/15 x 0.05 ) x 11/4
mọi người giúp mình mới .
\(x=\left[6\frac{3}{5}:6-0,125\cdot8+2\frac{2}{15}\cdot0,05\right]\cdot\frac{11}{4}\)
\(\Leftrightarrow x=\left[\frac{33}{5}:6-\frac{1}{8}\cdot8+\frac{32}{15}\cdot\frac{1}{20}\right]\cdot\frac{11}{4}\)
\(\Leftrightarrow x=\left[\frac{33}{5}\cdot\frac{1}{6}-\frac{1}{8}\cdot8+\frac{32}{15}\cdot\frac{1}{20}\right]\cdot\frac{11}{4}\)
\(\Leftrightarrow x=\left[\frac{11}{5}\cdot\frac{1}{2}-1+\frac{8}{15}\cdot\frac{1}{5}\right]\cdot\frac{11}{4}\)
\(\Leftrightarrow x=\left[\frac{11}{10}-1+\frac{8}{75}\right]\cdot\frac{11}{4}\)
\(\Leftrightarrow x=\left[\frac{1}{10}+\frac{8}{75}\right]\cdot\frac{11}{4}\)

0.3 + 0.3 : 0.25 + 0.3 : 0.5 + 0.3 : 0.125
0.3 + 0.3 : 0.25 + 0.3 : 0.5 + 0.3 : 0.125=700.9875
k nha!
mình nhanh nhất!
0.3 + 0.3 : 0.25 + 0.3 : 0.5 + 0.3 : 0.125
= 0.3 : 1 + 0.3 : 0.25 + 0.3 : 0.5 + 0.3 : 0.125
= 0.3 : ( 1 + 0.25 + 0.5 +0.125 )
= 0.3 : 1.875
= 0.16

1) tìm x biết:
x= (6và 3/5 : 6 - 0.125 x 8 + 2 và 2/5 x 0.03)x 11/4
Tìm x biết:
x=(6và3/5-0.125*8+2vvà 2/15*0.03)*25/3
x=(6và3/5-0.125*8+2vvà 2/15*0.03)*25/3
X=(33/5-1+32/15*3/100)*25/3
x=(28/5+8/125)*25/3
=708/125*25/3
=236/5
thực hiện các phép tính sau:
\(a,\left(4\frac{5}{37}-3\frac{4}{5}+8\frac{15}{29}\right)-\left(3\frac{5}{37}-6\frac{14}{29}\right)\)
\(b,\left(2\frac{5}{6}+1\frac{4}{9}\right):\left(10\frac{1}{12}-9\frac{1}{2}\right)\)
\(c,-\frac{2}{3}\left(8\frac{1}{2}-7.75\right):\frac{1}{3}+0.125:2\frac{2}{3}\)
A=-5/18+32/45-9/10+(-1/4+7/33-5/33)-(-15/12+6/11+8/15) = ?
